I have an Amana Refrigerator, model ASD2624HEB. The ice dispenser stopped dispensing cubes, but will still give crushed ice. Then about 6 months later, it stopped dispensing water (we still get crushed ice). We bypassed the filter and still no water. I think we verified that the lines are not frozen.
Try removing the ice bin from the front and see if there are any lodged clumps of ice. Run the bin under warm water until the ice melts. Dry the bin then try cubed ice.
You might have a jammed cube in there.
